EXPERIMENTAL DETERMINATION OF THE ELASTIC-PLASTIC MATERIAL BEHAVIOUR OF HYDROSTATIC EXTRUDED AZ31 AND AlSi1MgMn AS A FUNCTION OF TEMPERATURE

C. Brämer, M. Stockmann

Abstract

For predicting the forming behaviour of Al-Mg-compounds and changes in the interface strength during further processing it is essential to accurate determine the occurring state of stress on the interface. For this purpose precise material properties of the compound are needed. Tensile tests with hydrostatic extruded AZ31 and AlSi1MgMn revealed flow curves with strong dependencies on temperature, strain rate and thermal treatment. During dwell times the true stress relaxes significant under high temperatures.
